Shelf structure

ABSTRACT

A unitary shelf and food storage pan support structure for cabinets. An extruded member supported on cantilevered shelf brackets includes a pair of opposed runners which frame an imperforate shelf and are provided with a set of grooves that slidably support a food storage pan. The runners include another set of grooves that slidably engage the shelf brackets. The arrangement, in combination with selectively releasable detent means, affords either sliding withdrawal of the storage pan relative to the imperforate shelf, or sliding withdrawal of the pan and shelf as a unit.

PATENTEU JAN 1 1 972 SHEET 2 OF 2 SHELF STRUCTURE BACKGROUND OF THE INVENTION This invention relates to shelf structure, and more particularly cantilevered sliding shelf structure. While of broader applicability, the invention has particular utility in the field of household refrigerators.

Adjustable cantilevered shelves have met with considerable success in refrigerators, and it is an objective of this invention to provide novel and improved structure for adapting conventional, adjustably mounted cantilever support brackets of the type used for such shelves, to the support of both shelves and food storage pans, or the like.

SUMMARY OF THE INVENTION In achievement of the foregoing and other objectives, the invention provides, in cabinet structure, a pair of laterally spaced, parallely extending cantilevered shelf brackets, a slidable shelf runner on each said bracket, a shelf spanning the space between said brackets and supported by said runners, means defining a longitudinal groove on each said runner, and food storage pan means disposed below said shelf and slidably supported in said grooves, Selectively releasable detent means affords either sliding withdrawal of the storage pan means relative to the shelf, or slidable withdrawal of the shelf and pan means as a unit.

The manner in which the foregoing as well as other objectives and advantages of the invention may best be achieved will be more fully understood from the following description, taken in light of the accompanying drawing.

FIG. 6 is a sectional showing of the support means as seen looking generally in the direction of arrows 66 applied to the illustration thereof in FIG. 5.

DESCRIPTION OF THE PREFERRED EMBODIMENT With more detailed reference to the drawing, and first to FIGS. 1 and 4, there is illustrated a refrigerator 10 which in this case is of the so-called side-by-side type and comprises a left-hand freezing compartment, over which door 11 is closed, and a right-hand above-freezing food storage compartment 12 provided with a door 13. The latter door is disposed in open position for the sake of convenience of illustration. Compartment 12 is cooled by forced flow therethrough of relatively cold air from the freezing compartment, in accordance with conventional practice. Storage of foods in compartment 12 is accommodated by shelves designated generally by the reference numeral 14, and including cantilevered support brackets of the type seen at 15, and suspended from vertically extending, apertured support bars 16 on the rear wall of the compartment.

The invention is embodied in a combination slidable food storage pan and shelf assembly 17 disposed in the lower region of compartment 12. With reference also to FIGS. 2 and 3, the

lower pair of spaced brackets 15 is supported. in cantilever fashion, by hooks 18 thereon extending into and engaging edges of apertures 19 in bars 16. Each of brackets 15 includes an inwardly turned horizontally extending flange 20 and a vertically extending, longitudinally tapered main portion 21. A tie rod 26 is affixed at each end to a corresponding portion 21 of a bracket 15, whereby the brackets and rod are handleable as a unit.

A slide member 22 frames a glass shelf 23, and includes spaced parallel sides or runners 24 and an interconnecting rear side 25, each of identically extruded material, such as metal or plastic. The several sides conveniently can be formed of one extrusion bent to generally U-shape by known techniques, or it may be made up of separate, suitably joined lengths of extruded stock. Each side runner 24 includes a glass receiving groove 32, and an inverted L-shaped groove 27 that mates with portions 20 and 21 of the bracket 15 to provide for sliding support of the frame 22 and shelf 23 thereon. Each side runner 24 further includes an inwardly facing horizontally extending groove 28 that slidably receives a flanged upper edge 30 of a storage pan 29. Framing of glass shelf 23 is completed by a front, transversely extending member 31 provided with a groove 33 (FIG. 3) receiving the shelf, and which member 31 blends with and is fastened to, as by cementing, the forward ends of side runners 24.

As is best seen in FIG. 5, the member 22, the glass shelf 23, and-the food storage pan 29, which in the preferred embodiment is a crisper pan, are slidable as a unit on rails or brackets 15. Further, crisper pan 29 is slidable on member 22, and, as is seen also in FIG. 6, selectivity of sliding is accommodated by a detent, such as projection 34, on frame member 31 releasably retained in a recess, such as slot 35, formed in each of brackets 15. Although projection 34 is conveniently illustrated as being formed on front frame member 31, it will be understood that the invention contemplates that said projection may be provided instead on a corresponding runner 24.

In operation, and assuming the detent is positioned as shown in FIGS. 5 and 6, an upward and forward pull on member 31 will disengage the above described detent, and will slide the member 22, shelf 23, and crisper pan 29, as a unit, forwardly on brackets 15. As is best seen in FIG. 5, the vertical extent of groove 27 accommodates upward, pivotal movement of member 22 sufficient to move projection 34 out of slot 35. Alternatively, a forward pull on the downturned handle portion 37 of crisper pan 29 (FIG. 6) results in forward sliding movement of the pan with respect to the member 22, as is provided for by sliding engagement of pan flange 30 in groove 28.

It will be appreciated that the novel combination of this invention may be utilized at other convenient locations within the cabinet. For example it may be embodied in the shelf and bracket structure l4, 15 associated with a meat storage pan 36 located in the upper region of food compartment 12. Also, the assembly 17 may be moved to such other locations in the cabinet as may be provided for by the adjustability of the shelf brackets.

Summarizing, the invention herein disclosed provides improved structure for adapting conventional, adjustably mounted cantilever support brackets to the adjustable support of both shelves and pans.
